基于ZigBee的无线表决系统的设计与实现

Research and design of wireless voting system based on ZigBee

针对有线的电子表决系统布线繁琐、移动性差,基于Wi Fi技术的无线电子表决系统又存在抗干扰能力较差、功耗偏高等问题,提出基于Zig Bee技术的无线电子表决系统解决方案。该解决方案中,系统由主机、节点以及无线传感器网络(WSN)组成。系统在完成初始化和组网检测后,表决终端可实时响应主机发送的表决命令。表决终端实时采集表决数据,并通过基于CC2530的Zig Bee模块向主机回传表决数据。数据通过Zig Bee模块组建的无线传感器网络传输至协调器,最后通过串口交由主机进行处理并显示表决结果。实验结果表明,基于Zig Bee技术的无线电子表决系统解决了有线电子表决系统布线繁琐、移动性差的问题,同时相比基于Wi Fi的无线电子表决系统具有更强的抗干扰能力和更低的功耗。

Since the wire-based electronic voting system has problems of complicated wiring, and poor mobility, and wireless electronic voting system based on the technology of WiFi has problems as poor anti-interference ability and high power consumption, a solution about wireless electronic voting system based on ZigBee technology was proposed. The system consists of network nodes, host and Wireless Sensor Network （ WSN）. After completing initialization and network detection, the voting terminals can response the command sent by the host in real time. Then the voting terminals would collect data and send the data back to the host. The data firstly was transferred to the coordinator through the wireless network which set up by ZigBee modules and then was transmitted to the host through the serial port. The test results show that the wireless electronic voting system based on ZigBee technology solved the troubles of wiring and disadvantage of poor mobility in wire-based electronic voting system, at the same time, compared with the system based WiFi technology, the system based on ZigBee technology has stronger anti-interference ability and lower power consumption.
